As industrialized total wars, the First and Second World Wars required the unprecedented involvement of civilians. After both wars had ended, the demobilization of large numbers of soldiers, medical staff and workers, the care for invalid veterans, war widows and orphans, and the relocation of millions of prisoners of war, displaced persons, expellees and refugees created immense political, social, and economic problems and challenges for the postwar societies, which also had to deal with the costs and wounds of war. This chapter explores the economic, social, and cultural demobilization and the reordering of societies after the First and Second World Wars with a gender perspective and focusses Britain, France, Germany, the Soviet Union, and the United States. With these belligerents, victorious and defeated nations, market-based and communist societies, and democratic and authoritarian political systems can be compared. The chapter demonstrates the importance of the gender relations for the reconstruction of the postwar social order. After both wars, in all these societies, despite their differences, it was mainly the families, particularly the women, who had to heal the wounds of war.
